Question
The message "KRUDEYZMSYIOEAAUONYRYEEFJVDZ" was encoded using a transposition cipher with column order 3, 1, 2, 4. Decode the message. Enter it in all caps, with no spaces. Include any extra filler letters that were added at the end of the message.
Expert Solution

Step 1:
- Transposition Cipher - Method of encryption of plain text where plain text systematiccaly arranged into ther sequence.
- Encoded Message - KRUDEYZMSYIOEAAUONYRYEEFJVDZ
- Total number of alphabets - 28
- Column Order - 3, 1, 2, 4
- So the Key length will be 4
- Number of column - 4
- Number of Rows - Total number of encrypted alphabets / Total number of column
- Number of Rows - 7 as 28/4
- Therefore, in deciphering f plain text the number of rows is 7 and number of columns is 4.
- The encrypted text will be written column wise with the fixed row length which is 7.
